LOG BUNK.

Application mee Ju1y'15, 1924. seran No. 726,118.

To all whom t may concer/n Be it known that I, FREDERICK I/V. CHRIS- WELL, a citizen of the United States of America, and resident of the city of Seattle,

5 in the county of King and State of Tashhave invented certain new and useington of which ful Improvements in Log Bunks, the following is a specification. Y

My invention relates to log bunks designed for mounting upon trucks, cars and the like, for purpose of supporting and carrying logs during transit.

The object of my invention is to provide a type of construction for these logs which r shall be strong and simple, employing standard sizes and types of material, and one which is also designed for satisfactory holdingl of the logs.

My invention consists of a bunk in which the vertical webs are made of two sections of rolled steel in the form of bulb angles connected by a rolled section in the form of a channel bar, these being assembled in such manner as to provide a channel above the web of the connecting channel bar and between the upper ends of the bulb angles, in which is mounted and held the chock.

The type of construction which is preterred by me is shown in the accompanying drawings.

Figure l is a top or plan view of a bunk made in accordance with my invention.

Figure 2 is a side elevation of the same bunk with one oit' the side webs broken away near one end to show its interior construction.

Figure 3 is an end elevation of the bunk. In making this bunk I employ two bulb angles l, placed with their webs vertical, with a flange 10 at the bottom and extending outwardly. This brings the bulb ll of each angle at the top. Between these bulb angles is secured a channel bar 2, this being placed so that its web is located somewhat.

restrain theendwise movement of the chain,

and thereby hold the chock against outward movement. To more fully secure the cha-in in this position it is carried about the end of the bunk and dropped into a slot formed in a chain-retaining member 6 secured to the outer face of the bulb angle l.

By using a channel bar 2 as the connecting Y web for the bulb angles, the channel thus formed, and in which are mounted the log chocks 3, has vertical surfaces neXt to the chock. In consequence the chock may be made tovclo-sely lit between the upper ends of the two bulb angles and it is held securely in plance against any lateral movement or twisting, and is yet free to move lengthwise of the bunk.

WhatI claim as my invention is:

1. A log bunk comprising two bulb-angles and a channel bar secured to and between the bulb-angles with its web somewhat below the bulbs ot the angles and with the 'Hanges of the channel bar downward.

2. A log bunk comprising two bulb-anglesy and achannel bar secured to and between the bulb-angles with its web below the bulbs and its flanges downward, the web of the channel bar having a slot therein near each end to accommodate chock holding chains.

3. A log bunk compri-sing two bulb angles and a channel bar secured to and between the bulb angles with its web a short distance below the bulbs to provide a chock receiving channel, the flanges of the bulb angles eX- tending outwardly and of the channel bar downwardly, the web of the channel bar near each end having slots accommodating chock holding chains, and chain holding dogs at the ends of the bunk.
